1 State of California Lahontan Water Quality Control Board Update on Salt & Nutrient Management Plans

2 Overview Brief Background of CA Recycled Water Policy Salt-Nutrient (S-N) Plan requirements How we are working with the IRWM groups in our Region for S-N planning Status of S-N Plans

3 Recycled Water Policy Goal is to increase the use of recycled water while protecting water quality Four Main Parts of Policy: 1.Mandates Increase in Recycled Water Use/Provides Incentives 2.Streamlines Permits/Clarifies Regulation 3.Addresses Constituents of Emerging Concern (CECs) 4.Requires Regional Salt/Nutrient Management Plans for all CA basins by 2014

4 Recycled Water Policy Mandates Increase in Recycled Water Use & Provides Incentives Promote sustainable local water supply Increase use by one million acre-feet per year by 2020 & at least two million acre-feet per year by Priority funding for recycled water projects and storm water use projects

5 Recycled Water Policy Streamlines Permit Process & Clarifies Regulatory Roles Provides shorter review and processing for permits Provides uniform interpretation of statutes, regulations, and policies Clarifies the roles of State Agencies

6 Recycled Water Policy Establishes a program to evaluate the risks of Constituents of Emerging Concern (CECs) CECs – what and why? Advisory Panel, Report and Public Meetings Completed in 2010 CECs amendment to Recycled Water Policy in 2012 CECs in S-N Plans

7 Recycled Water Policy Regional Salt-Nutrient Management Plans Salts and Nutrients – what and why? Regional impacts, thus r egional evaluation of groundwater and regional management plan Locally driven, controlled and funded by water & wastewater entities, together with local salt/nutrient contributing stakeholders Plans for all basin in the state by May 14, year extension

8 Each S-N Plan Dependent on Site-Specific Factors Size and Complexity of basin Source water quality Storm water recharge Hydrogeology Aquifer water quality Watershed scale activities and stressors May include other constituents

9 Contents of S-N Plan Basin-wide monitoring plan for salts, nutrients and other constituents Annual monitoring of CECs Goals and objectives for water recycling and stormwater recharge/use Source identification, assimilative capacity, loading estimates, fate and transport Implementation measures to manage loading on a sustainable basis Antidegradation analysis

10 Other Requirements Participation by Regional Board staff Basin Plan amendment

11 Staff participation Regional Board members agree on S-N plan scope/concept prior to its completion (e.g. presentation of workplan outline at Regional Board meeting) Focus future Regional Board review on plan content & not on scope of effort Initial Regional Board Process

12 Lahontan Region About 24% of CA < 2% of population 345 groundwater basins/sub-basins

13

14 Prioritization of GW Basins Groundwater Ambient Monitoring and Assessment (GAMA) to ID Priority Basins 12 in Lahontan Basin North Lahontan (5) – Tahoe North/South/West; Martis/Truckee; Honey Lake South Lahontan (7) – Owens, Indian Wells, Tehachapi, Antelope, Lower/Middle/Upper Mojave

15 Overall Regional S-N Strategy/Approach Priority Groundwater Basins - Work with Integrated Regional Water Management (IRWM) groups Other Basins - Will address in groups as appropriate

16 IRWM Regions & Priority GW Basins Lahontan Basins Honey Lake Tahoe Sierra Tahoe North/South/West Martis/Truckee Inyo Mono Owens, Indian Wells Fremont Valley Tehachapi Antelope Valley Antelope Mojave Basin Lower/Middle/Upper Mojave

17 Status for Priority Basins Lahontan Basins (Honey Lake) DWR grant Tahoe Sierra (Tahoe N/S/W ;Martis/Truckee) DWR grant Inyo Mono (Owens, Indian Wells) New Indian Wells Group Fremont Valley (Tehachapi) possible draft plan for Fremont Antelope Valley (Antelope) concept/scope to Board, DWR grant, draft plan Mojave Basin (L/M/U Mojave) concept/scope to Board; SEP

18 Our “Other” 333 Basins Will address in groups as appropriate Reduce the burden on rural communities in the more remote parts of our Region while encouraging water recycling & protecting groundwater quality

19 Challenges No dedicated staff funding How to implement plans Few future funding sources 300+ “non-priority” basins Many DACs
